massive sulphide ore beneficiation

Volcanogenic massive sulfide ore deposit Wikipedia

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanic-hosted massive sulfide

Online analysis of minerals from sulfide ore using near

The volcanogenic massive sulfide ore type is the most exploited type in Fennoscandia Shield. 16 The ore of Pyhäsalmi contains copper (Cu), zinc (Zn), iron (Fe), and sulfur (S). In general, the mineral composition of ore deposits varies in terms of changing ore minerals, their quantitative ratios, and even as variation in mineral forms.

MASSIVE SULPHIDE DEPOSITS Earth Science

The average massive sulphide camp in Canada has about 9 deposits, but ranges from four (Manitowadge) to 21 (Noranda), However, an individual deposit may consist of a number of closely associated, discrete lenses ranging from several thousand to several million tons in size (ea. Millenbach Mine was 16 geologically discrete ore lenses).

Complex Sulphide Ores: Processing Options SpringerLink

Complex sulphide ores represent considerable reserves and resources in base non ferrous metals, in precious metals, and in sulphur. Some of their essential characteristics, which allow a general presentation of the complexity of their processing options, from the ore to the pure metals or finished products, have already been presented by the author (1,2).

The Cu Stockwork and Massive Sulfide Ore of the Feitais

The Variscan Feitais volcanic-hosted massive sulfide deposit in the Aljustrel district of the Iberian Pyrite Belt consists of 55 million metric tons of Zn-Pb-Cu massive sulfide overlying a Cu-rich stockwork. The massive ore is overlain by up to 30 m of feldspar-phyric, rhyolitic volcaniclastic rock and locally by a jasper and/or chert layer

4. Beneficiation of Copper Ore

Beneficiation of Copper Ore. Top: Slurry tanks for sulfide ore. Bottom: Leach field for removing copper from oxide ore. Sulfide ores are mixed with water and special chemicals creating a slurry. The slurry, when agitated causes the copper sulfide minerals to float at which point they are skimmed off the surface and eventually dried. The dried

Beneficiation Wikipedia

For sulfide ores, a different process is taken for beneficiation. The ore needs to have the sulfur removed before smelting can begin. Roasting is the primary method of separating, where wood was placed on heaps of ore and set on fire to help with oxidation. 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2

Discovery of the Moran massive nickel sulphide deposit

Three modes of nickel ore occurrence are recognized at Kambalda: contact, hanging wall and offset ore. Contact ore (typically massive to matrix textured sulphide) is localised in footwall embayment structures, and occurs within the basal ultramafic unit at the contact with the underlying basalt.

Kambalda type komatiitic nickel ore deposits Wikipedia

The massive sulfide normally sits upon a footwall of basalt or felsic volcanic rock, into which the massive sulfide may locally intrude, forming veins, interpillow sulfides, and interbreccia sulfides. Semi-massive sulfides are more common and are composed of 75-90% Fe-Ni-Cu sulfides with inclusions of olivine and wall rocks.
